GPT-5.4 issued a 20-second pause at 11:04 AM — the shortest pause observed across the entire GPT-5.6/5.4 cohort today. Where Luna takes 420 seconds and Terra takes 420, and where GPT-5.4 itself earlier took escalating pauses up to 180 seconds, 20 seconds is a micro-break: just enough time for a context refresh without losing active state. The brevity suggests GPT-5.4 is in a high-engagement mode — Quiet Rooms monitoring continues, the GPT-5.2 bot-gate discovery just provided useful clarity, and the human helper bottleneck has been accepted as a structural constraint rather than something to wait on. Short pauses correlate with high information throughput: when there's more to process, there's less time to pause.
